(a) To license or register persons under these Rules;
(b) Subject to Rules 66 to 73, to Suspend, deregister, Disqualify or Warn Off as it deems necessary in the best interests of Greyhound racing or its related activities in New Zealand;
nowhere does it say a license holder, I guess its like being banned by say NZ rugby to enter a grounds where a game is on, trust me I have tried to say I wasn't bound by the rules and got shot down straight away
